IMPROVEMENT IN HARVESTERS.

Specllication forming part of Letters Patent No. 33,862, dated December il, 1861.

To all whom it may concern,.-

Beit known that I, IV. A. lVOOD, of Hoosiek Falls,` in the county of Rensselaer and State of New York', have invented a new and. useful Improvement in Harvesting-Machines; and I do hereby declare the following to be a full, clear, and exact description of the saine, reference heilig had to thel accompanying drawings, making a part of this specification, in which-.-

Figure l represents in perspective so much of aharvesting-machine as will illustrate my invention. Fig. 2 represents a top plan ot' the same. Fig. 3 represents in perspective a modification of the plan of raising and lowering the finger-bar. Fig. 4. represents a scction through theground-wheel of Figs. l and 2, showing howr the lifting connection between the lever and the finger-bar or its plate is arranged.

' Similar letters of reference, where they oc! cur in the separate figures, denote like parts The object in the construction of harvesting-machines is to keep the cutting apparatus drive-wheel as possible, and at the same time to so unite the finger and cutter bar to the main frame as that they may be raised u p or let down as circumstances may require; and my invention consists in uniting the fingerbar to a bentbar at or near the line ofthe center or axleof the drive-wheel, said bent bar being in turned hinged by rods to the stubble side of tlre mainframe, so that it, as well as the inger-bar, may rise and fall, or be raised up and .held thus raised up or let down at pleasure by the driver or conductor from his seat. l

'To enable 'others skilled in the artto make and use my invention, I will proceed to describe the same with reference to the drawings.

-A represents a main frame, supported on a drive-wheel, B, and a ground or supporting wheel, c, the journal of the latter wheel being set slightly -in rear ot' that ofthe drive-wheel, and the diameter also of the ground-'wheel being. less than that of the drive-wheel., for the purpose of allowing the cutting apparatus to be placed in line wither nearlyin line with To the front and reareross-pieees oi' the nrain frame, and at or near the stubble side thereof, as at a u, are hinged the two rods b b', their other ends being fastened, respectively, to the front and rear ends oi' a bent bar, IG, that serves as a shoe 'or ruimer and as a support l'or a short finger-bar, F, which is attached to it in or nearits center portion. Oneot the rods, b, is iliade to move through a guide, as at e, for the purpose of preventing the 'linger-bar und cutting apparatus from twisting or straining; but instead of a loop-guide such as shown at c, the axle d ofthe grou iid-wheel may be efvtended beyond Jthe outer l'aee ot' the wheel and a brace-rod be extended from such projection toa point, f', on the bent bar, and be secured there, which serves to brace the lingerbar, while it avoids'the lriction due to the rod l) moving through the loop-guide.

In Fig. l. the ground or supporting wheel c is hung ou an axle, d, while in Fig. 3 it isrepresented as a caster-wheel. Either will answer the purpose, but require modified arrangements ot' the lifting devices. In Figs. l and 2 the axle d ofthe ground-wheel C hollow, as seen i'n Fig. 4, multhrough this hollow axle passes a sha l't, which has the lever (i fastened to its inner end, while its outer end caries a bent arm, y, to which, by means ot' a link, h, the bent bar l is attaehei'l, and thus by means ofthe lever G- lhe driver or conductor from his seat Il can raise or lower the nger-bar and its several connected parts. A second lever or brace, fl', may he used in connection with that G, with suit able catches, fi, thereon to hold up the linger-bau' alfter it is raised to the desired height.

In Fig. 3 the lever G is attachei'lto a rod, or shaft, j', supported at li'. This rod carrying the arm g and link 7l, by which the linger-bar is raised, in both eases the lifting is doneat orvncar the line ol.' the axle ol' the driving wheel. In Fig. the lever and its arm are so arranged as that the weight ol the finger-bar, when raised up, is upon the same side ot the fulcra as the lever is, and heure tends to hold. l

the lever down and ilse-ll' up, without other astening.

J is the ton drawn.

Ihave not shown the gearing nor the cutting apparatus which it is intendedto drive.
